LEVER-HANDLE FOR SELF- 6LOSING WORK.

Patented Sept. 22, 191

Application filed June 9, 1918. Serial No. 772,646.

To all whom it concern:

Be it knownth t I, PHILIP Munnnnu, citizen of the United States, reslding at Decatur, in the county of Macon and State sired angle thereabout, and which may be quickly secured to or removed from the work.

This invention also embodies the features of simplicity in the construction of the several parts, practicable in its application and use, and economy in the manufacture of the device.

Heretofore in self-closing work of all kinds, it has been customary to have the track-ways or other operating parts of selfclosing devices made iriteglral w-iththe handles thereof, a feature making it very awkward at times in correctly positioning the handle on the work. To overcome this objection is the purpose of this. invention and, in the embodiment herein shown and described and as applied toa self-closing cook, the present invention overcomes this (lisadvantagerby making the track-way or other operatin part of a self-closing structure separate mm the handle, adapting the track-way and the handle for interfitting at various angles about their common axis of rotation and with respect to each other, and to provide quickly detachable means for securing the handle in adjusted position on the track-way. ,4

Fror. the following detail description of the present embodiment of this invention will appear other more or less important features, the same being illustrated in the referred to accompanying, drawings in which Figure 1 is a side elevation of a selfclosing cock having the [improved lever han dle applied thereto. Fig. 2 is a top plan view of the handle mounted on the upper track-way of a self-closing work, the se-. curing means being removed. Fig. 3 is -a detail vertical section through the upper track-way and the handle, the latter being raised from interlocking engagement with the same. Fig. 4 is a detail enlarged perspective view of the upper track-way of the self-closing work.

Referring to these drawings, wherein the invention is disclosed as applied to a selfclosing cock, 10 designates the body of the cock in which is mounted a self-closing work shown sufficiently to illustrate the adaptation of the present invention thereto. The self-closing work comprises in part a lower track-way 11 fixed upon the body 10 and over which travel rollers 12 supported around a centrally disposed stem 13.

Mounted around the stem 13 for rotation thereabout is the operating member of the self-closing work, in the present instance being the upper track-way 14 which rests upon the rollers 12. The track-way 14 is provided with an internal flange 15 closely fitting the stem 13 and forming a shoulder or seat upon which engages a nut 16 threaded upon the upper end of the stem 13 andadapted to hold the track way 14 against the rollers 12 in the usual manner. The nut 16 is provided with one or more diametrically extending slots 17 in its upper I facethrough the desired one of which tends alocking pin 18, the pin passing through the upper end of the stem 13 to lock the nut 16 to the stem. The upper track-way 14 is further provided with an externally threaded. sleeve portion 19 rising about the nut 16 and providing together with the flange 15 a cup or recess into which the nut 16 is seated. 'At the base of the sleeve 19, or at that point where the sleeve joins the upper. track-way 14, an annular flange 20 1s formed, the same being provided with peripheral serrations, teeth, or being of other formation for a purpose which will presently appear. The flange 20 is spaced slightly above the track-way 14 to admit of the sharp cutting of the serrations in its periphery.

For manually operating the self-closing work to open the same, a handle 21 is provided, the handle being separate from and independent of the upper track-way 14. The inner end of the handle is formed into a hood or skirt 22 adapted to slidably fit over the track-ways-M and 11 and about the sleeve 19. The upper of the hood 22 is redufied in diameter or provided with an inlot turned flange as at 23, which portion 23 is provided with serrations, teeth, or is of other formation complen'iental to the periphery of the flange 20, whereby the flanges 20 and 23 may interlock when the hood 22 is dropped completely down over the trackways 1i and 11.

For securing the hood 22 in position after the handle 21 has been adjusted to the desired angle around the track-ways la and 11, a cap nut Ql is provided which cap nut is screw threaded upon the external threaded sleeve 19 and binds against the upper end of the hood 22, or upon the flange 23 and houses the upper end of the stem 13 and the nut 16.

It is thus seen that the handle 21 may be detached from the track way 14 by the removal of the nut 24 and the handle may be turned to any desired angle for convenience of the user of the self-closing work, and to accommodate the cook or other self- -closing work to congested places Where access can not be readily had to handles which are formed integrally with the npper-trackway 14; as is now the common form of construction. 1

it is to be understood that this invention comprehends any modification of this structure which will produce a handle attachment admitting of the adjustment of the handle to various positions about the upper track-way, the scope of theinvention being determined by the appended claims.

What is claimed is- 1 in self closing Work, a fixed lower trackway, a movable upper trackway, rollers between the track-Ways to raise the upper track-way upon the rotation thereof, a flange upon. the top of the-upper track-Way having teeth'in its periphery, a projection above the flange, a hood engaging over said track-ways and having an opening in its top and internal teeth in the Wall of the opening for engagement with the teeth of said flange to hold the hood from turning upon the upper track-Way, said hood also having a handle projecting therefrom for turning the upper track-way, and a cap threaded upon the said projection and en-- gaging the hood to secure the same to said In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

PHILIP MUELLER.
